To all 4whom it may concern I u n dl'eburg, `Logancounty, in the State of Ohio, have nvented certain new and useful Improvements in Fruit- Jars 5 and I hereby declare the following to. vbe'a full and exact description i thereof', reference ,being had to the accompanying drawing forming part of 'this specification.

`The nature or'essenceof my invention consistsin certain improved features, (to be fully described be- `low,) in a combination of devices for closing air-tight the top or mouth of a glass or other jar.

"In thedrawing hereinbeire mentionedv Figure 1 is a top view of a jar with `the cover off. Figure 2 is a verticalfsection through the center of `the top 'of the jar arid thefcover.

` i Figure 3shows the usual springfclasp for holding the cover down.

At the mouth of the jar A the top surface bis creased or corrugated so as to/make circular ridges orl depression`s,orboth, upon it, inorderthat the more 'promientparts may be pressed into the yielding surface of the packing or gasket d placed upon it, and .thus forni an air-tight joint beneath the packing with i less pressure than would otherwise be requiredlV For the same purpose a single edge of -rthe tin (or other sheet metal)` cover e is made to project downward so as to meet the, top surface of the gasket or packing d, and this edge being easily pressed into the said packing an air-tight joint is thus formed above the packing bya. verylight pressure on the lid or cover.. The two inclines i, up which on either side the clasp.I

H is pushed to press down and hold the lid, are/formed yof tiu or other sheet-metal, and so'arrauged that the top is a single cut or raw edge of the metal, which,

by friction and by the slight indentation. made, causes the clasp to stick more securelyI where4 it is placed in
